The 0pcordance with the presentinvention; -crating means for the piston 17 includes an Figure 2 is aninner end elevational view; extensible piston rod formed of telescopingFigure3is avertical longitudinal sectional sections, one end section ofthe piston rod view taken on line 3-3 of Figure 2,;showing beingconnected to the piston and the other the removable brush head, theinternally end section thereof being connected to an opthreaded tubularhandle, the extensible piston crating head swiveled upon the innerend ofrod for operating the piston and the operatthe tubular handle. Theextensible piston f ing head for the piston rod with the piston rod isformed of a series of telescoping secrod in its fully extended position;tions 18, rectangular in end elevation, each Figure 4 is a sectionalview, similar to Figsection comprising side walls flanged inwardme 3,showing the extensible piston rod in 1y at their lower ends as at 19 andflanged its fully retracted position; outwardly at their upper ends asat 20, the

' other end telescopes into said end section 18 of the piston rod and isflanged outwardly as at 23 for engagement with the outer flange 19 uponsaid piston rod section, the plug 21 being rectangular in cross sectionas illustrated in Figure 5.

The inner end section of the extensible piston rod is provided with aninner end wall 24 and said wall 24 has the inner end of a screw 25 fixedthereto as at 26, the screw freely extending through a central opening27 provided in the inner end wall 11 of the tubular handle 10 andcarried by an operating disk head 28 rotatably mounted upon the innerend of the tubular handle.

By rotating the operating head 28 in a counterclockwise direction, thepiston 17 that is illustrated in its fully extended position in Figure 3is threaded through the tubular handle to occupy a position adjacent theinner end wall 11 and during this movement, the sections 18 of theextensible piston rod telescope within each other as shown in Figure 4and provide a relatively large chamber within the tubular handle betweenthe piston 17 and brush head for the introduction of shaving cream orthe like upon removalof the brush head from the open end of the tubularhandle. Upon rotation of the operating head 28 in a clockwise direction,the piston 17 is threaded through the tubular handle toward the open endthereof for the discharge of the shaving cream onto the brush bristles13, the extensible piston rod rotating with the operating head 28 andpiston 17 with the rectangular form of piston rod sections providingpositive drive connections between adjacent sections and eliminating anytendency toward binding of the parts and assuring perfect operation ofthe device.

While there is herein shown and described the preferred embodiment ofthe invention, it is nevertheless to be understood that minor changesmay be made therein without departing from the spirit and scope of theinvention as claimed.

I claim 1. In a fountain shaving brush, a tubular internally threadedhandle having an open end, a brush head removably mounted in the openend, a piston threaded in the handle, a piston-rod for operating thepiston formed of telescoping sections rectangular in end view andinterlockingly connected together and an operating head for the pistonrod mounted on the inner end of the handle.

2. In a fountain shaving brush, a tubular internally threaded handlehaving an open end, a brush head removably mounted in the open end, apiston threaded in the handle, a piston rod for operating the pistonformed of telescoping sections rectangular in end view andinterlockingly connected together, an operating head for the piston rodmounted on the inner end of the handle, and a plug connection betweenthe piston and piston rod anchored to the piston and telescoping intothe adjacent piston rod section and being nonrotatable relative to'saidpiston rod section.

3. In a fountain shaving brush, a tubular internally threaded handlehaving an open end, a brush head removably mounted in the open end, apiston threaded in the handle, a piston rod for operating the pistonformed of telescoping sections rectangular in end view andinterlockingly connected together, an operating head for the piston rodmounted on the inner end of the handle, a plug connection between thepiston and piston rod anchored to the piston and telescoping into theadjacent pistonrod section, and said plug being rectangular incross-section and non-rotatable relative to said piston rod section.

In testimony whereof I afiix my signature.
